Going LeanGoing LeanAn Introduction to Lean
Principles
Objectives
• Understand what lean manufacturing is
• Know the difference between value and waste in our process
• Recognize the 8 types of waste• Become familiar with the lean
tools
Agenda
• Introduce Lean Manufacturing
• Define waste and value
• Communicate the types of waste
• Introduce basic “lean tools”
• Agree on a path forward
What is Lean Manufacturing?
• The optimization of value in our process so that we have the ability to make exactly what is needed, when it is needed and in the quantity it is needed by our customer
• The relentless identification and elimination of waste from our process so that we can flow at the rate of customer demand
How Will Lean Help Us?
• Reduce Lead Time to our customers by eliminating waste from our system
• Reduce frustrations by removing barriers to doing our jobs
• Encourage everyone to get involved in improving the process
• Increased customer satisfaction• Optimally utilize resources while
meeting our customer’s needs
What is Value?
• A measurement of the worth of a product, or service, by a customer based on it’s usefulness in satisfying a customer need
• An activity, process or operation that changes the product from one form to another in order to get it closer to the customer’s specifications
• It is something that the customer is willing to pay for
What is Waste?
• Any activity that adds costs or time but does not add value
• Consuming more resources (time, money, space, etc) than are necessary to produce the goods, or services, that the customer wants
• Pure Waste: Actions that could be stopped without effecting the customer
• Incidental Waste: Actions that need to be done based on how the current system operates but do not add value

The 8 Types of Waste
OverproductionInventoryTransportationMotion (Operations)ProcessingDefects / QualityWaitingPeople’s Skills
Overproduction
• Common causes:– Producing more than is required to
make up for yield loss– Scheduling production to forecasted
demand– Long changeovers or avoiding
changeovers lead to large lot production
• Supplying the process with more than is needed to meet order requirements, sooner and faster than it is needed, causes almost all other types of waste
• This is the worst waste of all, because it helps cause all the others
Inventory
• Common causes:– Overproduction– Poor equipment layout– Long changeover times– Defective, or questionable, parts– Mismatched production speeds
• Requires people, equipment and space to count, transport, store and maintain it
• If we do not get orders the material will become obsolete, and be thrown away
• Inventory is often used to help hide other wastes

Transportation
• Common causes:– Extra Inventory
– Retention points before and after operations
– Excessive distance between operations (layout)
– Single skill focused operations
• Double or triple handling, moving in and out of storage areas and warehouses
• Material can get damaged if it’s moved too much• It adds no value and is often used to get the extra
inventory out of the way
Motion (Operators)
• Common causes:– Poor workstation layout– Isolated operations– Shared tools– Fatigue– Workstation congestion
• Walking without working (away from workstation) • Searching for tools, materials or information• Reaching, bending or unnecessary motion due to
poor housekeeping or workplace layout• Process is not designed with employees in mind
Processing
• Common causes:– Lack of standard work or
processes– Equipment over designed– Process not updated with
technology changes– Lack of effective problem solving
• Doing more than is necessary to produce an effectively functioning product
• Extra setup steps, over-specification of the process, extra processing steps
Defects / Quality
• Common causes:– Emphasis on downstream
inspection; questionable material passed on
– Lack of standard work
– Material handling (transportation)
– Process design/equipment
• Defective or scrap materials• Cost of inspecting defects• Responding to customer complaints• Rework or re-inspection of questionable materials
Waiting
• Common causes:– Mismatched production rates
– Poor layout
– Machine breakdowns• Ours or upstream
– Insufficiently staffed
• Operator waiting for machines to run or cycle• Machine waiting for operator• Waiting for parts, instructions, approval,
information, maintenance, decisions…
People’s Skills
• Common causes:– Management does not involve
employees in problem solving– Narrowly defined jobs and
expectations– Old school management,
worker relationships
• Employees are seen as a source of labor only, not seen as true process experts
• People are told what to do, and asked not to think• Employees are not involved in finding solutions,
opportunities to improve our process are missed
Waste – the simpler part…
Being Able to See IT!(once we know what it is)

5 Lean Principles make up the 5 Lean Principles make up the Lean Strategy for Our CellLean Strategy for Our Cell
1. Specify value
2. Map the flow of value
3. Make value flow
4. Pull from the customer
5. Seek perfection
1. Specify Value for Our Customer(s)
• Value added steps lead to a transformation of the material from one form to another which gets the product closer to the customer’s specifications
• Providing the right product, at the right time, in the right quantity, at the right quality, at the right price, in the right place in accordance to the customers requirements
A value stream is all of the value-adding activity AND all of the non-value adding activity (pure waste and incidental waste) required to provide a product/service to a customer
2. Map the Flow of Value in Our Cell

• Targets are meant to break the vision down into actionable items that should be accomplishable in 3-5years.
Growth of our people, our process, our organization & our sales:
1) To have Grade A employees

Standard Work Sheet
KanbanA visual system that easily communicates the need for parts to be either replenished or consumed. Designed to improve material flow and control inventory levels.
• Workers know what product to produce based on actual usage
• Minimizes inventory by tying production to consumption
• Places controls on how much inventory is carried within the system
X X X(make one move one)
Quick ChangeoverLooks at trying to optimize changeover times by reducing activities that occur during the changeover, standardizing tooling/fixtures, adopting parallel activities and minimizing adjustments.
• Improve repeatability through standardized processes
• Improved flow of material
• Reduction in inventory
• Standardize expectations
Zero Defect QualityThe principle that defects are prevented by controlling the performance of a process so that it cannot produce defects through mistake proofing and failsafe methods.
• Improved quality and customer satisfaction
• Solutions at the source – employees aid in problem solving and in developing creative, more effective corrective actions
KaizenA system involving every employee that is based on making little changes on a regular basis, anywhere changes can be made.
• Continuous small improvements
• Changes are implemented quickly
• Everyone gets involved

How Do We Succeed with Lean?• As a team – open minded, supportive• Understand the concepts and accept all aspects of
the lean process, including those that may cause undesirable effect in the short term
• Aligned focus from the top to the bottom• Effectively use lean methodologies• Carefully plan implementation to remove waste• Allocate the proper resources• Becoming truly lean is a journey and will not be
made without some discomfort
